Three everyday frustrations, three design decisions.
Most cordless fillet knives fix one thing and create two more. These are the three complaints that come back most often in owner reviews — and what we did about each.
“I spent an hour on a cooler of panfish.”
A long manual session at the cleaning table wrecks your hands and your mood — and one blade length never suits every fish in the bucket.
Both blades ship in the box: a 9-inch stiff blade that drives through thick cuts, and a 7-inch flexible blade that follows the bone line on smaller fish. No second purchase, no choosing at checkout.
Worth saying plainly: a sharp manual fillet knife in skilled hands still yields more meat. An electric buys you time on a big batch, not a better fillet.
“The release button is right where my thumb goes.”
It's a complaint anglers make about cordless knives across the category: the trigger and the blade release end up stacked, so the blade pops mid-cut.
Ours are separated. The trigger sits under the index finger, the release is up by the thumb in its own position, and a red safety lock has to be clicked before the trigger arms at all. Two deliberate steps before the blade moves.
“The battery died, so the whole knife went in the trash.”
Sealed internal batteries turn a small failure into a full replacement — and they give you no warning before they quit.
This pack isn't sealed in. Press both release buttons and the 12V 2000 mAh pack slides out of the back, so it charges and stores away from the knife. A three-bar LED gauge on the body of the knife shows the charge level before you start, instead of halfway through the cooler.
One thing to be straight about: we don't sell spare packs, so this isn't a keep-two-batteries setup. What removable gives you here is a gauge you can read before you start and a pack that charges and stores away from the knife.
Everything in cut foam, ready to carry.
Four jobs the manual signs off on.
Fish, lean cooked meat, bread, vegetables. That list comes from the manual — we didn't extend it.
Not for: bone-in meat · frozen or partly thawed food · very hard produce such as raw pumpkin · submerging the handle in water · running more than 5 minutes continuously without letting the motor cool. Every one of these is a manual instruction, not our caution.
Exactly as the manual lists them.
Not listed, on purpose. Runtime per charge, IP water rating and battery cycle life aren't in the manual, so they're not on this page. The manual does say the housing must not be rinsed or immersed — this knife is not waterproof. Warranty terms follow the storefront's published policy; the 90-day return window and free defect replacement apply either way.
Straight answers.
Stiff blade or flexible — which do I use?
Both come in the box. Use the 9″ stiff blade for thick cuts and anything you slice straight through; use the 7″ flex when you need to follow the curve of a bone on a smaller fish.
How long does one charge last?
We don't publish a figure. The manual gives the pack capacity (12V, 2000 mAh) and the charge time (5–6 hours) but no runtime, and we won't quote a number we haven't measured. The three-bar LED gauge on the knife body tells you where you stand before you start.
Do you sell spare blades or a spare battery?
No — the complete kit is the only thing we sell, and we don't stock blades or battery packs as separate parts. Both blades and the battery are included. If something arrives faulty or fails on you, that's a returns and defect matter, not a spare-parts one — email support@wellmallpro.com.
Can the blades be sharpened?
No. Serrated electric blades wear rather than dull evenly and can't be honed back like a straight edge — that's true across this category, not just here. Shipping both blades in the box is our answer to it.
Is it waterproof?
No, and there's no IP rating. The manual says not to rinse or immerse the handle. Wipe it with a damp cloth and dry it before storage; the blades detach and wash normally.
What can't it cut?
Bone-in meat, frozen or partly thawed food, and very hard raw produce like pumpkin. Thaw fish before filleting.
How long can I run it at once?
Five minutes continuous, then let the motor cool. It's a manufacturer limit to prevent overheating — on a big batch, work in rounds.
Shipping and returns?
Ships from our U.S. warehouse in 3–5 business days, free on orders over $36.99. 90 days to return it; defects replaced free.
